JiaBaiDa SP04S034 3S 4S 12V 100A 120A 150A 200A LiFePo4 Li-ion BMS
Introduction of SP04S034 Software BMS - 3S 4S 12V 100A 120A 150A 200A Smart BMS with UART RS485 Communication
JBD-SP04S034 smart bms is a software protection board scheme specially designed for 3~4 strings of lithium battery packs. SP04S034 software bms support both lifepo4 and li-ion battery with 100A~200A continous current. By the way, SP04S034 also supports app and pc communication. The product adopts architecture of front-end acquisition chip + MCU, and some parameters can be flexibly adjusted through the host computer according to customer needs.
